摘要

By combining three-dimensional digital microtomography techniques with the lattice Boltzmann method, a new methodology is used to analyse the relative permeability of multiphase flow in porous media. The results indicate that the two coupling coefficients K-12 and K-21 have the same magnitude, therefore the Onsager reciprocity still holds. The results also agree well with the results of pipe flow numerical experiments.
